MACHINE FOR SETTING' LAome-HooKs.

SPECIFICATION forming part of Letters Patent No. 774,271, dated November 8, 1904. 7 Application filed September 25, 1903. Serial No- 1'74,6'71. (N0 model.)

To (tl whom it nutg concern:

Be it known that I, IRA F. PEoK, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Setting Lacing-Hooks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to machines for setting lacing-hooks wherein a plunger reciprocates in conjunction with a stationary upper anvil to set the eyelet portion of the hook, and

has for its object the ends commonly sought in such machines.

This invention resides primarily in the novel structure and combination of the setting-tools and their actuating mechanism.

In the drawings forming part of this specification, Figure 1 is aside elevation, partly in vertical section, of a machine embodying my invention; Fig. 2, a similar view of the driving-shaft and one of the cams, showing one cam-channel in dotted lines; Fig. 3, acentral vertical section of the reciprocating plunger and adjacent parts; Fig." 4, a transverse section of the same on line as :0 of Fig. 3; Fig. 5, a side elevation of the entire machine; and Fig. 6, a'transverse section of the mechanism, taken on line g y of Fig. 1.

Like reference-numerals indicate like parts throughout the views.

The frame or body 1 of my machine is provided with a yoke 2, carrying an anvil 3, vertically adjustable by milled nuts 4 upon its upper portion. The usual downwardly-inclined run 5 guides the hooks to the throat portion 54, which leads to the setting mechanism. Transversely mounted in the machine-frame is the shaft 6, driven by the pulley 7 and carrying the disks 8 and 10. The shaft 6 passes through a slot 11 in a reciproeating bar 12, and this bar 12 has pivoted to its forward extremity toggle-links 14 and 13, whose opposite ends are respectively connected to the plunger 16 and to the pin 15,

vertically adjustable in the frame by nuts on a threaded sleeve 56 An adjusting screw 17, mounted in the frame, supports the lower edge of the bar 12. This bar is recipprocated by a roller 38, traversing the channel 39 of the disk 10.

A sliding dropper 9, with detent 19 for separating the front hook from a series upon the run, is attached to the extremity of a link 20, Whose opposite end is connected with one arm of the bell crank lever 21, mounted upon guide-block 55 on the frame. The other lever-arm, 22, is provided with a slot which engages a pin 23, projecting from the inner face of a slide 24, mounted in the guide-block 55, depending from the frame. The rear end of the slide is provided with a roller 25, which registers with the channel 26 in the outer face of disk 8.

For conveying the separated hook to the setting-tools is a pusher 27 pivoted at its lower extremity to a projection 28 upon the frame adjacent the plunger. Attached to the pusher 27, above its pivoted extremity, is a link 29, connected with a bar 30. whose opposite end is retained by a pin 31 and cushioned by a spring 32 in the elevated arm 33. The latter is provided with a slot 34 to admit a pin 35, fixed to the machine-frame, and is longitudinally reciprocated by roller 36, which travels in a channel 37 in the disk 8.

Reciprocating circular motion is imparted to the setting die-head by means of the following mechanism: A lever 40 is pivoted to the machine-body with its lower end engaging a pin tl projecting from the slide 24 through the slot :2 in the guide-block. The upper end of lever 40 is connected by alink 43 to a rack 44:, mounted to slide in the machineframe adjacent the plunger. The rack engages a pinion 45, which meshes with a segmentally-toothed sleeve 46, rotatably mounted in the machine-frame and through which the plunger 16 reciprocates vertically as a sliding lit. In this plunger is a vertical stem 49, provided With a setting die-head L7, normally resting upon the top of plunger. A portion of the die-head is cut out, as at 18. to allow removal of the lacing-hook after the setting operation. Below the head is vertically mounted in a pocket l6 within the plunger a spring-pin 53 with a concave top and adapted to hold the hook in frictional contact with the under side of the die-head IT during the swaging operation. A pin 50 projects from the stem, 49, traversing the plunger 16 through a radial slot 52 and engaging a vertical keyway 51 in the inner face of sleeve a6. Thus any rotary motion of the sleeve is imparted to the die-head t? without imparting such motion to the plunger 16. Astop-pin in the plunger 16 prevents excessive upper travel of the pin The operation of my machine is as follows: A hook slides from the run 5 into dropper 9. The revolution of the disk 8 upon the driving-shaft 6 lowers the dropper 9, and the hook enters the throat portion 54. of the run, where it is thrust forward by the pusher 2T,

actuated by the disk 8, into position intermediate the head 4:7 and spring-pin 53. while the rack 44: has advanced and rotated the die-head 47 into the position shown in broken lines in Fig. 6. 'Ihereupon the reciprocating bar 12 is thrown forward, and the plunger 16, with thehook engaged thereon to the die-head 4:7, is caused to vertically rise through the sleeve or sector member 16 to its fullest height and the lacing-hook set in contact with the anvil 3. The plunger then recedes a certain distance far enough from the point of the setting-die to clear the hook, then makes a partial revolution in order to bring the opening in the die-head or top plate I7 opposite the opening or pocket 16 in the plunger 16 to allow the hook to be expelled. After the partial turn of the die,'as above described, which brought the opening of the die-head and the die in alinement, the plunger continues its downward travel, and at the end of said travel the top plate has been turned Meanback into position to receive another hook or the position indicated in Fig. 6 of the dra\ ings. This movement of the die-head in relation to the die and their respective segmental openings is important, since the registration of the latter facilitates the discharge of the hook that has been previously worked upon and is a distinct advantage, as will be readily seen. It will also be noted that the setting die or plate at the instant of the setting operation has a decidedly firm bearing upon the top of the supporting die or plunger, giving stability and permanency to the structure, which is most desirable.
